Primary injury occurs at the moment of trauma and includes contusion, damage to blood vessels, and axonal shearing, in which the axons of neurons are stretched and torn. [1] The blood brain barrier and meninges may be damaged in the primary injury, and neurons may die. [7] Cells are killed in a nonspecific manner in primary injury. [8]
[12] [13] All traumatic brain injuries are head injuries, but the latter term may also refer to injury to other parts of the head; [14] [15] [16] however, the terms head injury and brain injury are often used interchangeably.

The primary concerns regarding oral injuries are that the airway is clear and that there are no concurrent injuries to other parts of the head or neck. Oral injuries may occur in the soft tissue of the face, the hard tissue of the mandible, or as dental trauma .
Cerebral contusion is bruising of the brain tissue. The piamater is not breached in contusion in contrary to lacerations. The majority of contusions occur in the frontal and temporal lobes. Complications may include cerebral edema and transtentorial herniation. The goal of treatment should be to treat the increased intracranial pressure. The ...
Cerebral contusion (Latin: contusio cerebri), a form of traumatic brain injury, is a bruise of the brain tissue. [2] Like bruises in other tissues, cerebral contusion can be associated with multiple microhemorrhages, small blood vessel leaks into brain tissue. Contusion occurs in 20–30% of severe head injuries.

Facial trauma can involve soft tissue injuries such as burns, lacerations and bruises, or fractures of the facial bones such as nasal fractures and fractures of the jaw, as well as trauma such as eye injuries. Symptoms are specific to the type of injury; for example, fractures may involve pain, swelling, loss of function, or changes in the ...
According to King’s research, most cheer-related concussions resulted in a loss of time from sport of one to three weeks, but concussion was the leading cause of cheer injuries resulting in time ...
Abdominal CT showing left renal artery injury. Blunt abdominal trauma (BAT) represents 75% of all blunt trauma and is the most common example of this injury. [3] Seventy-five percent of BAT occurs in motor vehicle crashes, [4] in which rapid deceleration may propel the driver into the steering wheel, dashboard, or seatbelt, [5] causing contusions in less serious cases, or rupture of internal ...
